Dear R-Helpers
I am attempting to get a legend in the outer margins of a graph that has a
similar flexibility to mtext(), within base graphics. This is used in a
tool that will end up with graphs of many different coordinates, exported
in many different sizes. I'm trying to come up with a general solution.
I've used "bottom right" before but I found it interferes with the graphs
frequently.
Here was my best attempt at something general, but then I encountered the
graph re-sizing issue:
x <- 1:100
y <- x +rnorm(100, 0,10)
plot(x,y, xlab="", main="Shrink and Enlarge This Graph")
abline(0,1 ,lty=2)
legend(x=grconvertX(1, from = "ndc", to = "user"),
y=grconvertY(0, from = "ndc", to = "user"),
lty=2,
legend="The legend doesn't rescale nicely",
xjust=1, yjust=0,
bty="n",
xpd=TRUE)
mtext("This example has some text in the outer margin.\nIt rescales
nicely.",
side = 1, line=3.5, adj=0)
Thanks!
Peter
